I am unable to view several websites that require logging in as I get an error that "This Connection is Untrusted." I view the certificate and confirm the exception, but the same Untrusted site simply reloads and it is seemingly impossible to get past.

I have checked other posts of this nature in this forum and the time/date on my computer appears to be valid. This is so frustrating as I even had difficulty in posting this question and had to go on IE in order to access this page, since it required that I create an account to login. I have been a loyal FireFox user for ''many ''years and am feeling distraut by this hassle.

Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.

Every time I try to log into ANY website that is secured, I get an error message "This connection is untrusted."

The error message is:
This Connection is Untrusted
You have asked Firefox to connect securely to www.facebook.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
www.facebook.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)
If you understand what's going on, you can tell Firefox to start trusting this site's identification. Even if you trust the site, this error could mean that someone is tampering with your connection.
Don't add an exception unless you know there's a good reason why this site doesn't use trusted identification.
Steps I have take so far:
Verified that system clock is correct
Cleared all cache, history, cookies, etc.; didn't help
Started Firefox in Safe Mode; didn't help
Disabled all Firefox extensions; didn't help
uninstalled and reinstalled Firefox using Control Panel; didn't help
Ran Microsoft Safety Scan for malware; nothing was found
Other information:
This problem exists ONLY in my user profile and ONLY in Firefox. All 5 other users can run Firefox with no problem. I can run IE and Chrome with no problem.
Problem exists in ALL secured (https) sites.
I use Avast and Windows Firewall. Had never heard of ESET or BitDefender before searching these forums.
A lot of the sites don't give me the option to Make an Exception. The two that I tried to make exceptions for, still wouldn't open.
Run Windows 7 64-bit

unfortunately the fiddler2 issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.
 reference: https://support.mozilla.org/en-US/questions/982532#answer-520145
afterwards, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

I am continuously recieving the same error message (this connection is untrusted)

When I try to access my emails (Gmail) I recieve this error message; what should I do? My laptop PC is a Windows Vista and Firefox is 33.0. My laptop currently runs Kaspersky Internet Security 2015 as protection.

mail.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)

What about on https://www.google.com/ ? Can you load that? If so, take a look at the "Issued by" section by clicking the padlock in the address bar, then "More Information" then "View Certificate".

Problems with receiving error message "This Connection is Untrusted" for any https sites. On version 17.0.1 of firefox. IE does not get error.

whenever I go to an https site, I get this error message. My other browsers are not having the same issue. I deleted cert8.db as one site suggested. Stopped using firefox due to this issue. example: www.comcast.net, once I sign into email, I get this error message. Amazon.com - same issue. So, these are very common sites. This only started in past two weeks.

Does updating to Firefox 18 (which comes out today) help? It fixed a few issues with certificates.

Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site

This started for me 1/17/2011 on the savingsbank.com website:
Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site https://www.savingsbank.com
NO other browsers - Explorer, Chrome, Safari - give this error box on this site. Please advise if this has to do with the bank site? or Firefox compatibility.
Saw in a forum someone else having this problem and they were told it had to do with their Date and time being off?? I've been on several computers, all with the correct date and time and they've all shown this Insecure Certificate statement on my bank site with Firefox and no other browser.

I've looked at the banking site with IE8 and it does NOT show me that "This connection is Untrusted" window. (please see attached screen shot of viewing the site with IE8) It opens fine and has "Identified by Network Solutions" showing on the address bar as it always does.
The latest version of Opera (not earlier ones) does show a problem with the website's security certificate.
We've contacted the bank about this, and they say there's no problem with their certificate but are looking into it.
My question remains, why only Firefox and one version of Opera claim this and NO other browser?

Ugent help - Every time i go to a secure website firefox latest version says This Connection is Untrusted. This was never there before and now its appearing

Every time i go to a secure website using firefox latest version i get an error saying "This Connection is Untrusted" This was never there before and now its appearing. My computer clock and date is correct and i have tested out all plugins that they are updated. Also did a scan on all viruses and spyware nothing there any help please.

Sorry, I didn't look at all the images.
You can see that the certificate is issued by your security software (Firewall): ESET SSL Filter CA 
So you will have to disable that filter or install the ESET root certificate that chains to that certificate.

I am getting "this connection is untrusted" error messages from Firefox for Desktop when I try to log into certain websites, such as Facebook. Why?

I get this error message "this connection is untrusted" after I re-installed Windows Vista and all my programs. This happened before but after reformatting my computer everything was good. Why am I getting this? Could it be a virus of some sort? It happens when I use Windows Internet Explorer as well....

Hi,
Please check the time/date on the PC. The ideal setting would be to '''Automatically synchronize ...''' in Date and Time > Internet Time.

Urgent:Unable to view the root organisational unit created in the PPOCE

Hi Experts,
I have created a root organisational unit using the Tcode PPOCE.But I am unable to view the same in the selection area using the Structure search.It is appearing in the search term area but not in structure search.
Please help it is very urgent
Thanks in advance

Try Clicking on 'Unrelated Objects' in the PPOCE screen. It should show your root org unit. I think you have just created the root org unit without the complete structure.

How do I get rid of the "This Connection is Untrusted" message?

I have used my firefox browser for 1 1/2 without any problems. Now all the sites I go to give me the warning message that "This Connection is Untrusted." I can no longer access email or my university website to see my grades- nothing works. Even when I click that I understand the risks and verify the certificate, I can still only get so far- but it's never all the way to where I need to be.
How can I get rid of this annoying problem?

Thanks jscher2000 and cor-el for your help! It turns out it was a date and time issue. I'm glad to say it's all fixed now! Thanks again!

Why can't I connect to web sites that require my user name and password. window pops up saying this connection is untrusted.

hello, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
* what is the '''error code''' shown under ''technical details'' on the error page?
in case the error code equals ''sec_error_unknown_issuer'', please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
* which '''issuer information''' does the certificate contain?
thank you!
[["This Connection is Untrusted" error message appears - What to do]]

Google and Facebook show 'This connection is untrusted'; other sites are fine. What's wrong?

Hi there,
Yesterday I could log into sites like Facebook, Google and others fine, and now when I try to log in to them it comes up with the following message:
'This connection is untrusted.
www.facebook.com uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)'
I managed to get onto other sites like BBC News and Outlook without any error messages. Strangely, Google Images comes up fine from a bookmarked link, but then goes to untrusted as soon as you search for anything. I've seen this message come up on the support site before, and have tried the following suggestions:
-Cleared the cache
-Cleared cookies (including individual page cookies)
-Deleted internet temp files
-Cleared Downloads folder in Firefox
-Opened Firefox in Safe Mode to rule out add-on problems
-Chosen 'No proxy server' in the Network options
-Reloaded the page using Ctrl-Shift-R
-Reloaded the page from a History tab when it was working (yesterday)
-Used the bookmarked link
-Typed the link in directly
-Reset Firefox
-Deleted the 'cert8' file in the Firefox folder
-Synchronised system time and date with time.windows
-Full antivirus scan on computer (which showed nothing)
-Checked web security settings in Bullguard (no interference there)
-Uninstalled/reinstalled Firefox
I managed to get Google working eventually, then the Mozilla Support pages said they were untrusted, so I'm currently posting from Chrome, which is becoming my backup browser more frequently :(
Apologies for the lack of proper Troubleshooting info! Here's the best I can do:

Any idea what else I can try? Facebook I'm not too worried about, but I need Google for work and pretty much everything else!
EDIT: I gave up, went and had a pint of tea and when I came back everything seemed to be alright again! Not sure what the hell happened. Does anyone else have any idea why this comes up, or is it just something that happens now and again?

this is similar to your question.just go-through it or if you stuck then reply back for more info on this problem : https://support.mozilla.org/en-US/questions/974711

This Connection is Untrusted...I accidently put in the wrong login info and a specific site and now I am blocked from it, how do I unblock this.

After trying to login to a specific website three times, Firefox has now blocked me from this site. "This Connection is Untrusted" I have used this site for many years and need to be able to access it.

Rename or delete the file cert_override.txt (cert_override.txt.old) in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] to remove all permanent exceptions that you have saved.

"This connection is untrusted" shows up CONSTNATLY!!! and I cannot move the page down to get to the bottem of I understand the risks to override it. How do I do that or how do I TURN IT OFF!!!

Even sending this message gets the" This connection is untrusted"!!!!!How is that for stupid!!! How do I turn it off or do I have to use some other site and wipe firefox off my computer.

Just got this warning for facebook, Amazon, and Google, I have just told my clients to stop using firefox until the problem is fixed, it is a support nightmare because you have inexperienced users calling in convinced that they have a virus on their computer, and that they need to unplug the internet to prevent anything bad from happening.
I had one customer call in and say, "it says get me out of here, Oh my God what have I done I should never have gone online"
You know what can we have a better more accurate statement, on that warning, like Hi, thanks for stopping by this website may be sharing a security certificate with a parent organization, it may not really be a bad thing we just wanted you to know about it before you go on your merry way. Oh and by the way were going to make you jump through hoops and clicks check boxes and do this and do that before we let you go on your merry way, wait, " Are you really sure that you want to be doing this?" Do you know what your doing, perhaps you should call your ISP for advice, and get support from someone who has nothing to do with this issue.
Thanks Guys, appreciate all the calls, perhaps I should give them your email address. $%^$%#$

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted"

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted". Even when I do accept the risks the site no longer looks the way it's looked for years. Twitter doesn't even give me the option to accept the risks at all and shows this error (Error code: sec_error_unknown_issuer). I've tried resetting Firefox, I've checked the time and date, and I've removed and added Firefox to see if that would work. Nothing seems to be working so I can see the sites the way they normally would be instead of "coded". Can anybody help me please?!!! Thanks

ok, unfortunately the fiddler2.com issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.
